Hi, the maxima looks great!
The PB cars were pretty much unheard of where I was racing back in the day, but they definately seem really advanced for their time. Belt drive, 2-speed gearbox, etc.
Must confess I've never seen one in the flesh, and certainly not a 2-speed car. Have you? Wonder how well that works.
Anyhow, I happen to have a set of used, original PB wheels that might help out with your project. They've never been glued, and are in good but certainly not perfect condition. Nevertheless, I gather that they are just about impossible to find these days. If you're interested in having them, PM me and I'm sure we can work something out.
Looking forward to seeing another classic back on the road... Nice.
